ELECTRIC STEERING LOCK - DESCRIPTION

The steering lock allows a particular management of the vehicle protection system and engine starting.

The system is managed by the steering lock control unit which controls and regulates the entire steering column locking/unlocking system electrically controlled by means of special actuators.

The steering lock control unit, an integral node of the CAN, is the power distributor for the vehicle providing the ignition-controlled power supplies INT, INT/A, 15/54 and 50.

See E1010 POWER SUPPLY

Depending on the position of the key (TEG) inside the starting device, the steering lock control unit determines:f the enablement request for the +15 supply to the Body Computer (ON position), the +50 starting for vehicle (START position) and, if the result is positive, the power distribution to the vehicle and to the various load (INT, INT/A,15/54).

The starting system involves that together with the rotation of the key to the START position the clutch pedal (or in recovery conditions, the brake pedal) for versions with a manual gearbox or the brake pedal for versions with automatic transmission, is pressed.

On versions with automatic transmission the additional condition of the gear lever in P (PARK) must be observed. For further details,

See E5010 STARTING AND RECHARING

The release of the steering is activated when the TEG is inserted in the ignition device and is recognized.

The locking of the steering takes place with the TEG in the OFF position as long as the safety condition that involves the continuity of the steering release when the vehicle speed is above 4 km/h is respected. In this case the user is advised by means of a signal in the NQS: "The steering will not be locked".

The steering lock device allows the vehicle protection and engine start-up system to be managed in a specific way.

The system is managed by the steering lock control unit that controls and governs the entire steering column lock/release system electrically via special actuators.

The steering lock control unit node, part of the CAN network, distributes vehicle power to supply ignition-operated power supplies INT, INT/A, 15/54 and 50.

See E1010 POWER SUPPLY

Accordig to the position of the key (TEG) inside the ignition device, the steering lock control unit determines: the +15 power supply enablement request to the Body Computer (ON position), vehicle start-up +50 (START position) and, if this is successful, the distribution of power to the vehicle and the associated loads (INT, INT/A, 15/54).

During the start-up stage, as the key is turned to the START position, the clutch pedal (or the brake pedal during recovery) is pressed simultaneously for versions with a manual gearbox while the brake pedal is pressed on versions with an automatic transmission.

On versions with an automatic transmission, the gearlever must be in position P (PARK) as an additional condition. For further details,

See E5010 STARTING AND RECHARING

The steering release is activated when the TEG is inserted in the ignition device with the associated recognition.

The steering is locked with the TEG in OFF position, unless the safety condition that requires continuity of steering release at a vehicle speed higher than 4 km/h is not respected. In this case, the user is notified by a signal via the NQS. "The steering will not be locked".
